My High School's drumline during the summer would practice every Wednesday from 1 to 3 and one of our instructors couldn't make it to to practice because he is in bad health (he suffered a stroke 2 years ago and just recently he had a tia) so our other instructor contacted the entire drumline and had everyone meet for our sectional early, when we got there he told us to pack our stuff in the band truck and jump in his van.
We went to our instructors house and had our sectional there he was over joyed.
He enjoyed it so much he contacted the local weekly paper and had them write an article about it. http://www.webbweekly.com/artleisure.htm
The article is called Music, Mentor and Marching Musicians its about half way down the page.
